potion helmet

when you drink any potion it extends the potion effect to 20 minutes. If it a harmful potion it makes it so that you take double damage or time/speed for it, to balance it out. (Max. 2)

I mean have you ever wanted to do some underwater exploration but don’t have a conduit, then you could get water breathing for 20 minutes. Or if you want to go mining at night or in a dark cave but don’t have sticks or coal then you could have night vision. Same goes for any of the other potions. The only downside is that witches are more powerful now.
